5 Best Sweep Alternatives ESG Platforms for 2026

These are the 5 main Sweep alternatives covered in the comparison:

1. Dcycle
2. Persefoni
3. Watershed
4. Normative
5. Greenly

Sweep is a Paris and London-based carbon management platform recognised as a leader in IDC’s MarketScape for carbon accounting.

Its “collect once, use everywhere” approach to emissions data resonates with large enterprises managing complex supply chains.

However, companies that need to connect environmental data with broader ESG requirements, or that require accessible pricing for mid-market budgets, often explore alternatives.

The comparison below covers the best Sweep alternatives for companies that need broader environmental data coverage, CSRD outputs and transparent pricing.

5 best Sweep alternatives

1. Dcycle

Dcycle is purpose-built for companies that need to structure European environmental and operational data across multiple teams and frameworks.

The platform covers carbon accounting, CSRD requirements, EU Taxonomy alignment and decarbonisation planning in one environment.

Where Sweep focuses primarily on carbon data collection, Dcycle extends the same automation philosophy across a broader environmental-data landscape.

Dcycle is a data platform rather than a reporting tool. It helps companies structure information from purchases, suppliers, energy, workforce activity and operational systems so the same data can support reporting and compliance, savings analysis and operational decisions.

With automated environmental data collection, teams can reduce manual requests and maintain consistent records as requirements change.

Supplier information can also be organised through structured supplier engagement workflows, allowing businesses to request evidence, compare responses and retain traceability across their value chains.

The platform supports:

• Complete CSRD outputs: ESRS datapoint mapping with XBRL-ready output, extending beyond carbon metrics.

• EU Taxonomy assessment: Built-in eligibility and alignment analysis, an area Sweep does not cover.

• More than 200 automated data integrations: Collection of environmental, workforce and governance information from existing systems in weeks rather than months.

• Expert advisory included: Sustainability specialists support customers across all pricing tiers, not only enterprise plans.

• Transparent pricing: Tiered plans suitable for mid-market companies as well as large enterprises.

• Multi-framework support: CSRD, EINF, EU Taxonomy, the GHG Protocol and other outputs from one structured source.

• Platform available in English, Spanish and German: Native-language support for European teams.

The pricing structure offers transparent tiers suitable for companies ranging from 50 to more than 10,000 employees.

2. Persefoni

Persefoni is a US-based carbon accounting platform with strong PCAF alignment for financial institutions.

It provides robust Scope 1–3 measurement and climate-disclosure capabilities oriented towards SEC and ISSB standards.

The platform is best suited to US-headquartered enterprises and financial institutions that need PCAF-aligned carbon accounting. Its European CSRD coverage is still developing.

Pricing is based on custom enterprise contracts.

3. Watershed

Watershed is an enterprise carbon platform with advanced decarbonisation scenario modelling and a built-in carbon-credit marketplace.

It is a strong option for companies that want to connect emissions measurement with active reduction planning.

The platform is best suited to large enterprises focused on ambitious net-zero commitments and carbon-credit strategies. Its coverage of CSRD and other European regulatory outputs remains limited.

Pricing is based on custom enterprise contracts.

4. Normative

Normative provides emissions measurement backed by strong Nordic market expertise and an academic methodology.

It is a good option for companies that prioritise rigorous, science-based carbon calculations.

The platform is best suited to Nordic and Northern European companies focused on carbon-accounting accuracy. Its coverage of CSRD and EU Taxonomy requirements is less comprehensive.

Pricing is custom and oriented towards medium-sized and large enterprises.

5. Greenly

Greenly offers lightweight carbon accounting with bank linking for automated data collection.

It provides a fast onboarding experience for small companies beginning to organise their environmental data.

The platform is best suited to SMEs that are not yet subject to CSRD and need accessible emissions tracking. It may be less suitable for companies facing complex regulatory, assurance or multi-entity requirements.

Greenly offers pricing tiers designed to be accessible to smaller companies.

Why companies look beyond Sweep

Sweep remains a strong carbon management platform, particularly for large businesses with complex supply chains. However, it may not cover every environmental-data and regulatory requirement.

Common reasons for comparing other platforms include:

• Carbon-first rather than complete framework coverage: Sweep focuses heavily on carbon accounting and Scope 3 supply-chain data. Companies needing full ESRS datapoint mapping, EU Taxonomy alignment or double materiality assessments may find gaps.

• Enterprise pricing: Sweep targets large organisations through custom contracts. Mid-market companies and SMEs may struggle to justify the investment.

• Limited regulatory breadth: Beyond carbon, European companies face CSRD, EU Taxonomy, EINF and national disclosure obligations. A carbon-only platform can require companies to connect multiple systems manually.

• Scope 3 complexity: While Sweep excels at Scope 3 supplier engagement, companies at an earlier stage may find the platform more complex than they need for moving from data collection to reporting, savings analysis and operational decisions.

When to stay with Sweep

Sweep remains a strong choice if you:

• Operate a large enterprise with complex, multi-tier supply chains requiring deep Scope 3 engagement.

• Need a dedicated carbon management platform and handle other environmental outputs separately.

• Already have Sweep deployed and integrated with your supplier network.

• Primarily need carbon data for investor disclosures rather than complete CSRD, EU Taxonomy and operational outputs.

When to choose an alternative

Consider switching from Sweep if you need:

• CSRD and ESRS outputs with datapoint mapping and XBRL-ready information.

• EU Taxonomy alignment as part of the same workflow.

• Broader coverage beyond carbon, including environmental, workforce and governance information.

• Accessible pricing for a mid-market budget.

• Expert advisory support without an enterprise-tier commitment.

• Faster preparation for upcoming regulatory deadlines alongside savings analysis and operational use cases.

Companies reviewing their options should also consider how regulatory changes may affect their future data needs.

The CSRD Omnibus changes make it even more important to choose a platform that can adapt its outputs without requiring teams to rebuild the underlying environmental data.

How to compare the alternatives

The right platform depends on how the company plans to use its data.

Sweep may remain suitable when the priority is sophisticated carbon accounting, extensive Scope 3 engagement and an established enterprise supplier network.

A broader data platform may be more appropriate when carbon information also needs to support CSRD, EU Taxonomy, EINF, cost analysis, supplier decisions and operational improvements.

Companies should compare:

• The environmental data sources each platform can collect.

• The frameworks and outputs supported beyond carbon accounting.

• The level of supplier engagement required.

• The ability to manage multiple entities, countries and business units.

• The availability of traceability and audit evidence.

• Implementation time and internal resources required.

• Pricing transparency and access to specialist support.

Companies should also consider whether their chosen platform can reuse existing data when a framework changes. If every new disclosure requires another collection process, the organisation remains dependent on duplicated work even after implementing new software.

Conclusion

Sweep remains a strong carbon management option for large organisations with complex supply chains and advanced Scope 3 requirements.

However, companies that need broader environmental data coverage, European regulatory outputs and transparent pricing may require a more flexible platform.

The right choice depends on whether the priority is carbon accounting alone or a data platform that can structure information once for reporting and compliance, savings analysis and operational decisions.

Companies comparing their options should also review carbon-footprint software selection criteria, implementation requirements and future regulatory needs before making a decision.
